WJEC A Level Maths Unit 3

Just wandering how you guy find it? I’ve got really confused when I was attempting the integration question x^2sinx and most questions tbh. It was hard for me, I was only able to do half of the questions…

Found Q15 the hardest. Pretty sure I got zero marks for that. Others were fine.

I believe it's the semi-circle + rectangle one. That question was zzz.

Didn’t even know what topic it was, what substitution did you use for the integration question?

last one? I used whatever was in the bracket of the denominator... x+3 if I remember correctly? I forgot the actual answer but I remember getting it correct cause I checked against calc. Think fraction was 1/576.
